HEY GUYS I HAVE A 406 WITH DART PRO 1 215 HEADS 10.1 COMP 5.7 RODS CAM IS A HYD ROLLER 240/248--543-555 LFT 16-44-56-12 --106 LOBE SEP. JUST ABOUT HOW MUCH HP/TQ DO THINK ITS MAKING--OH WOULD AFR 210s WORK BETTER DO THEY FLOW BETTER THEN THE DARTS



THANKS JOHNNY

 

Both are good heads. Are the darts fully CNC'd like the AFRs? That usually gives more flow and may make more power but not always the case. Lots of variables to look at. If you wanted more power, i'd have someone port those Darts and go with a slightly bigger cam to match.

Either way thats a stout combination and should be making around if not abit over 500hp on motor. Hard to say. My buddy has a 406 with a similar hydraulic roller but abit wider lsa with AFR 195's and runs mid high 11's at 117mph. His car I think is abit heavier than mine was as I have gone mid 11's at 118-119 with a 383 with the same heads and slightly smaller duration cam with more lift. I estimated my motor to be around 500hp.

Best way to find out is weigh the car and take it to the drag strip
